DlisBrowser 2.1

Text format files like LAS can be viewed using any ASCII editor; its simple specification allows easy understanding their content.
Binary formats files like LIS and DLIS (RP66) cannot be viewed with a text editor. These formats are very complex, so it is difficult to understand their content with a hex editor.
DlisBrowser allows to view full structure of LIS and DLIS files in a convenient form showing all logical records comprising the files including auxiliary records which are usually not shown by special processing programs.
DlisBrowser shows the logical records in a convenient form as an hierarchical tree. Each record is shown as a branch which contains other branches, e.g. Reel Header Logical Record (RHLR) contains multiple Tape Header Logical Records (THLR), each THLR contains multiple File Header Logical Record (FHLR), each FHLR may contain Information Records (type 34), Data Format Specification Record (type 64), Data (type 0) and other records comprising FHLR.
